After 3 surfs and two flat water sessions with the 9.0 fin I can say that it was a great investment.....easily my best performing investment of 08

. My 11'6 Naish feels more lively in the surf and a heap easier to turn on the wave. coming from a short board backround it is nice to lean into a bottom turn and she comes with me instead of going straight ahead. Small change in stability as the board now seems to roll rail to rail quicker when paddling in chop etc, due to the smaller side surface area of fin pushing against the water (I suppose??) Well worth the $55 invest.
